Coin wrapper dispensing mechanism



United States Patent ENVELOPE FOR LETTERS, PACKAGES OR THE LIKE AND A METHOD FOR MAKING SUCH ENVELOPES Emanuel Dziemczyk, RR. 2, Balzac-Alta, Alberta, Canada Filed June 12, 1967, Ser. No. 645,167 Int. Cl. 1331c 41/60 US. Cl. 9361 1 Claim ABSTRACT OF THE DISCLOSURE Courses of paper are joined at their longitudinal parallel edges by strips made of a mixture of textile fibers and cellulose. The courses thus joined are unwound from a roll and led to an envelope making machine where one of the flaps is joined to the main body of the formed envelope by this strip.

An envelope having the closing flap joined to the body by a strip separable along a straight line and made of textile fibers and cellulose.

BACKGROUND OF THE INVENTION The invention relates to envelopes for letters, packages and the like with an opening area closed by a separation strip or tear strip and to a method of making the same.

There is known a filler paper or envelope for wrapping or enclosing an object, in which at least two separate parts are joined by a closing band which is secured to each of the parts by an easily separable adhesive. This proposal is not adapted for mailing, because the closing band may be easily pulled off and replaced, so that the secrecy of the mails is not assured.

There is also known a letter envelope with a separation or tear strip of relatively weak material provided with perforations which can be torn manuallygThis proposal is also not satisfactory. Paper is made of wood fibers which are arranged across and transversely to the mass. The conditions under which the tearing and separation take place along the perforations, result in a tearing at the places of least resistance. Accordingly, paper can only be torn cleanly by means of suitable accessories, such as scissors or knives.

The envelope for letters, packages or the like with only one opening closed by a tear strip, is characterized according to the invention, by a strip structure which permits tearing along a straight sharp line. It is thus possible to tear by hand along a straight line. At the same time the tear strip is not weakened in any manner, so that it withstands the stresses of the mails. The edge of the letter is not damaged when the letter is opened, since it is never disposed close to the closing flap of the envelope, and is moreover spaced a certain distance therefrom, which is much greater than the tear line in the tear strip.

According to the method of the invention, parallelly extending paper courses' of a desired width are bridged by a tear strip and secured by gumming, and are unrolled from a roll and moved to an envelope-making machine.

An embodiment of the invention is illustrated below.

In the drawing:

FIG. 1 is a plan view of the courses bridged by a tear strip and FIG. 2 is a plan view of an envelope formed according to the invention.

As shown in FIG. 1, parallel paper courses 1, 2 and 3 are bridged by tear strips 4 and are secured to these with gumming. The separation strips known per se, consist of textile fibers and cellulose and are of such a structure that they can be easily separated. Numeral 5 indicates a roll on which are wound paper courses connected with separation strips, only to be worked on at another station at a given time. Obviously the widths of the paper courses and those of the separation strips may vary in each case, depending on the types of envelopes desired. Similarly, instead of paper courses, other materials may be employed.

FIG. 2 illustrates a cutout envelope blank, in which the separation strip 4 is disposed in the area where the envelope will later be opened, while the four envelope edges 8, are shown in dotted lines.

I claim:

1. A method of forming an envelope blank comprising providing a plurality of parallel paper courses, spacing the courses from one another, joining the courses along adjacent edges with a tear strip consisting of textile fibers and cellulose, said blank consisting of a body portion and flap portion, said body portion formed from one of said courses and the flap portion formed from another one of said adjacent courses, said tear strip joining said one course and another one of said adjacent courses forms the hinge between said body portion and said flap portion of the blank.

a corporation of Wisconsin Filed Jan. 9, 1968, Ser. No. 696,657 Int. Cl. B31c 3/00 US. CI. 9381 11) Claims ABSTRACT OF THE DISCLOSURE A dispensing mechanism for a pre-crimped coin wrapper forming machine includes a gripping assembly which accepts wrappers in the form of a tube from a spindle that ejects the wrapper from a forming mandrel. The gripping assembly grips the wrapper so that the spindle can retract for the subsequent ejection of the next wrapper. The gripping assembly is moved through an arc by a parallelogram linkage to deposit the wrapper in the entrance of a chute. The chute is filled by the continuous depositing of wrappers therein by the gripping apparatus until the chute is completely filled to the exit of the chute. A movable chute member is pivoted by wrappers being pushed to the exit and a switch is actuated by the movable chute member to open the energizing circuit for the motor which drives the machine elements. This'halts the forming of wrappers. The manual removal of wrappers from the exit of the chute permits the movable chute member to pivot to actuate the switch so that the motor is energized to form more wrappers until the chute is again filled.

BACKGROUND OF THE INVENTION This invention relates to coin wrapper forming machines, and particularly to a mechanism for maintaining a constant supply of formed coin Wrappers which is automatically replenished when a part of the supply is withdrawn.

Machines have been developed which are employed by the users of coin wrappers to form tube shaped wrappers that are crimped at one end. The wrappers are used in conjunction with coin counting machines to package the coins in standard rolls. The machine accepts paper stock either in the form of pre-cut blanks or on a roll and continuously forms the wrappers and ejects the same from the machine. The ejected wrappers have heretofore simply dropped from the machine and collected in bins.

It has been the practice to operate the machine to form a sufficient quantity of wrappers to satisfy the requirements for a days operations, for example. That is, a relatively large quantity of the wrappers is first formed and then the wrappers are used to package the output of coins from a coin counting machine. If too many wrappers are formed they must be stored until the next day on which they are to be used.

It is the purpose of this invention to provide a dispensing mechanism for a coin wrapper forming machine which will control the operation of the machine to form a given limited quantity of wrappers which are stored in the dispensing mechanism and which will cause the wrapper forming machine to automatically replenish such supply of wrappers whenever some of the wrappers are removed from the supply.

The dispensing mechanism accepts formed wrappers from the machine and places them in a chute. When the chute is filled the dispensing mechanism causes the machine to halt the forming of wrappers. The machine with 3,489,069 Patented Jan. 13, 1970 the dispensing mechanism can be placed next to a coin counting machine with which the wrappers are used. The operator removes wrappers as needed from the chute and the absence of a full chute is sensed by the dispensing mechanism to cause the forming machine to again operate to form more wrappers which are deposited in the chute until the chute is again filled. In such manner, a constant supply of formed coin wrappers is assured and only as many coin wrappers are formed as are needed immediately.

SUMMARY OF THE INVENTION A wrapper dispensing mechanism in accordance with the invention, in combination with a wrapper forming machine including forming means for forming a blank into a wrapper tube, feeding means for feeding blanks to the forming means, ejection means for ejecting each formed tube, and a source of power connected to continuously drive the forming means, the feeding means and the ejection means, comprises a Wrapper chute having an entrance and an exit, wrapper gripping means adapted to receive each ejected tube and carry the same to the entrance of the chute, and means in the chute responsive to the presence of wrappers at the chute exit and operative on the source of power to halt the forming and ejecting of wrappers when the chute is filled with wrappers.

In the description which follows, a preferred embodiment of the invention is shown and described in sufficient detail to enable those skilled in the art to make and use the same. Changes can be made to the preferred embodiment shown without departing from the true scope of the invention.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a top plan view of a portion of a coin wrapper forming machine with the Wrapper dispensing mechanism of the invention incorporated therein;

FIG. 2 is a view in vertical section taken in the plane of the line 22 of FIG. 1;

FIG. 3 is a front view in elevation of the dispensing mechanism; and

FIG. 4 is a right end view in elevation of the dispensing mechanism of FIG. 3.

DESCRIPTION OF THE PREFERRED EMBODIMENT The dispensing mechanism is shown incorporated in a coin wrapper forming machine of the type described in the copending aplication of Arnold R. Buchholz and Arnold J. Krause for Pre-Crimped Coin Wrapper Forming Machine, Ser. No. 659,935, filed Aug. 11, 1967, and assigned to the assignee of this application. Only so much of the forming machine will be described herein as is necessary for an understanding of the present invention.

Briefly, the forming machine withdraws a web of paper from a roll of paper stock and moves the web over a track between spaced stanchions 10 and 11 which rise from a base. Periodically, the web is automatically severed to form a wrapper blank which enters a forming cylinder 12. A mandrel 13 is disposed within the forming cylinder 12 and spaced therefrom (see FIG. 3). The mandrel 13 is rotated by a motor connected by means of a belt 14 to a shaft connected to the mandrel. The web is wound about the mandrel 13 as it is rotated within the cylinder 12 to form a tube. A crimping blade 15 is brought to bear upon the end of the formed tube and against a spindle head 16 that is mounted on the end of a spindle 17 journaled in the mandrel 13. The crimping blade 15 forms a crimp at one end of the tube and the formed wrapper is then ejected from the mandrel 13 by extending the spindle 17 through the mandrel with the wrapper being carried with the spindle.
